Huiyang District, Huizhou City Tianxin Yong Jin Sha battery factory was founded in 1997, is a professional development of production Button batteries, environmentally friendly batteries, dry batteries, lithium manganese batteries, rechargeable batteries based professional manufacturers. Generation plants using imported automatic production lines, imported raw materials, the factory after the high temperature and stored at room temperature, and then a 100% inspection to ensure that the battery stable quality. LR44 battery of environmental protection obtained national invention patents, the industry has high visibility, environmentally friendly battery defect rate significantly lower than the control standard IEC requirements.

As a battery-producing countries, China's battery industry in 1995 has occupied the world for more than half the battery production. However, due to excessive previous batteries contain mercury, which we usually refer to mercury, lead pollution and poisoning, so the battery safety issues more prominent.

And because the battery is a high frequency of use and universality, so threatening mercury-containing batteries more prominent. It is reported that a miniature mercury Alkaline Button batteries can contaminate 600,000 liters of water is equivalent to a lifetime of drinking water. Although since 1995, the United States and Europe have issued a ban on the sale of mercury-containing batteries with the relevant provisions, clearly defined, alkaline manganese batteries can not add mercury, the mercury content of no more than 0.0005% of the total battery, but because the world does not technology can produce mercury-free button batteries, can only allow Button batteries mercury content of no more than 2% of the total mass of the battery.

In other countries, Japan and the United States more than a decade, Europe and other famous battery manufacturers for mercury button batteries mercury-free a lot of research. However, there are technical problems are not resolved, there is no one company can successfully produce mercury-free alkaline button batteries, resulting in the global market have been using mercury-containing alkaline button batteries. Each year one billion button batteries are produced and used to make Chinese people and the rest of the world still faces the risk of exposure to mercury.

The problem with Xin Jin Yong Battery Co. invention solved. After years of research trials, Xin Yong-Jin R & D team in 2000, mastered the technical formula, successfully mercury-free alkaline button batteries. October 3, 2002, Xin Jin Yong application of the "mercury-free alkaline button battery" utility model patent successfully obtain authorization. In order to avoid patent issues encountered in the overseas market, the company has simultaneously in the United States, Germany, Britain and other EU countries to apply for this many patents. However, China's Button batteries mercury-free roads are quite bumpy. Over the years, repeatedly mentioned as competitors invalid request, without mercury Button batteries of 10-year patent protection period is about to expire, the ultimate fate of the patent concern.
